LiveCode doesn't include a Unicode display engine - it takes the steam
of characters, breaks it down into words and then asks the operating
system's display engine to render those words. This means that the

I've not tested with Devanagari, but the font shaping supplied by the
operating system does work for Arabic letters (the ZWJ and ZWNJ
codepoints cause the shaping to use initial/medial/final forms
correctly) so maybe the machine you're running on doesn't do Indic
shaping? Try entering the same characters into a text editor application
to see if it works (make sure you're using the same font in both the
editor and LiveCode). If not, let me know as there is something strange
